Answer:
[tex] \huge \: 19[/tex]
Step-by-step explanation:
to understand this
you need to know about:
- equation
- triangles congruency
- PEMDAS
TIPS AND FORMULAS:
- when two triangles are congruent the included angles and sides of the triangles are equal
let's solve:
[tex]step - 1 : define[/tex]
[tex]2x - 9 = x + 5[/tex]
[tex]step - 2 :solve[/tex]
[tex]2x = x + 5+ 9[/tex]
[tex]2x = x + 14[/tex]
[tex]2x - x = 14[/tex]
[tex]x = 14[/tex]
given:
KL=2x-9
=2.14-9
=28-9
=19
